Magnetic graphs for cavity quantum electrodynamics
Sunkyu Yu, Xianji Piao, Namkyoo Park
Strengthening light-matter coupling has become a central challenge in cavity quantum electrodynamics (QED), enabling ultrafast gate operations, qubit protection, and deterministic…
Mapping open quantum dynamics onto graphs
Kyuho Kim, Dayeong Lee, Seungkyun Park +3
Graph-theoretic frameworks have been widely employed in quantum physics to address the high-dimensional complexity of quantum systems. Although open quantum dynamics incorporates s…
Induced Directional Switching of Platicon Microcombs in Photonic Crystal Ring Resonators
Erwan Lucas, Su-Peng Yu, Jizhao Zang +1
Microcombs in normal-dispersion photonic crystal ring resonators (PhCRs) are a versatile building block for next-generation integrated photonic circuits, yet they inherently suffer…
Multi-objective design of photon blockade for bright single-photon sources
Sunkyu Yu, Xianji Piao, Namkyoo Park
High-quality single-photon sources, realized through saturable emitters, photon blockade, or heralded pair generation, are indispensable building blocks for photonic quantum platfo…
Tailoring Defects in Photonic Time Crystals for Coherent Energy Control
Dayeong Lee, Jongheon Yeo, Gitae Lee +3
Recent advances in time-varying photonics have revealed new degrees of freedom for manipulating optical states, arising from the distinctive nature of the temporal axis: causality…
Topological heavy-tailed networks
Sunkyu Yu, Xianji Piao, Namkyoo Park
